By that, they mean they don't want Palantir to see what is going on in those systems. Palantir has an unmodifiable blockchain to track all additions, changes and modifications, and deletions and by whom. No way to cheat. In many ways, Palantir is so much safer than any other system. But my guess is there are things they don't want the Trump DSI/NSA/CIA/Military Intelligence to see.

> unmodifiable blockchain

Ahhh, this old trope. Fork it - trivial to do when you have consensus.

I don't even understand what an "unmodifiable blockchain" held by a single private entity could mean.

They

- have the data of yesterday

- have backups of the data of yesterday

- are going to write today's data on top of it to continue the chain

(insert magic here)

- somehow we are super sure, tomorrow, that today's data has not been tampered with

If somebody can shine some light on the magic part, I'm interested

The point isn't that you can't add bad data: obviously you can.

The point is that if the hashes of the blocks are published, you can't later go back and tamper with that data.

You don't have to guess, that's exactly what the headline says: "...over fears of national security leaks". And several times in the body of the article.

Correct. Why should any country want its sensitive government data to be visible to other countries, and to Trumps government at that?

Why doesn't the Trump admin open up it's data to inspection by European, Chinese, Russian etc auditors? What does it have to fear?
